No.
You've probably done something wrong

Where abouts in the code?

#include <SPI.h>

//Set Slave Select Pin
//MOSI, MISO, CLK are handled automatically
int CSN = 10;
int SO = 12;
int SI = 11;
int CLK = 13 ;
unsigned int angle;
int dis = 0;


void setup() {
  
  Serial.begin(115200);

  //Set Pin Modes
  pinMode(CSN, OUTPUT);
  pinMode(SI, OUTPUT);
  pinMode(SO, INPUT);
  pinMode(CLK, OUTPUT);
  //Set Slave Select High to Start i.e disable chip
  digitalWrite(CSN, HIGH);
  //Initialize SPI 
  SPI.begin();
}

void loop() {

  SPI.beginTransaction(SPISettings(10000000, MSBFIRST, SPI_MODE1));
  
  //Send the Command Frame
  digitalWrite(CSN, LOW);
  delayMicroseconds(1);
  SPI.transfer16(0xFFFF);
  digitalWrite(CSN,HIGH);

  //Read data frame
  digitalWrite(CSN, LOW);
  delayMicroseconds(1);
  angle = SPI.transfer16(0xC000);
  digitalWrite(CSN, HIGH);
  SPI.endTransaction;

  angle = (angle & (0x3FFF));
  
  int pos = ( (unsigned long) angle)*360UL/16384UL;
  int dis = (pos * (3.1415/180));
 unsigned long start_time=micros(); //record start time
unsigned long delta_t = micros() - start_time; //the difference

  
Serial.print ("Angle in degrees =\t");
Serial.print (pos);
Serial.print("\t Angle in Rads =\t");
Serial.print (dis);
Serial.print("\t Time =\t");
Serial.println (delta_t);


  delay(500);
